        1. Method Overview The wheel hub is cleaned with purified water, dried, and its surface topcoat, coating paint, and primer are scraped off with a scraper. Microwave digestion is adopted, and the concentration of chromium is determined by flame atomic absorption spectrometry at a wavelength of 357.9 nm. 2.
